CAR-TRUCK.

srncrrronrxon forming n a Letters Patent No. 717,780, dated January 6, 1903. Application filed May 8,1902- $eria1hla 106,468. (No model.)

To all whom it may concern.-

Be it known that 1,1 AMES TIMMS, a resident of Columbus, in the county of Franklin and State of Ohio, have inventedcertain new and.

useful Improvements in Car-Trucks; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

: My invention relates to an improvement in car-trucks, the object of the invention being to simplify and lighten car construction by dispensing altogether with a truck-bolster consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

. In the accompanying drawings, Figure 1 is a view, partially in section, illustrating my improvements. Fig. 2 is an end view, and Fig. 3 is a view in vertical transverse section through the center of Fig. 1.

1 represents my improved truck-transom, which connects the side frames 2 of the truck and is preferably made hollow and of general rectangular shape,as shown. The truck-transom is preferably open at its ends, provided with numerous perforations to lighten the 3 5 construction, and is provided near its ends on its lower member with pockets 3 for springs 4. Four springs are located in each pocket,

(but it is to be understood that the number of springs can be varied at will,) and said springs are surmounted by caps 63, flanged at each side to prevent lateral displacement of side bearings 7, supported thereon. The side bearings 7 are widest at their upper ends and are rounded at both ends, the lower rounded 5 end resting on cap 6and the upper rounded end supporting fiat bearings 8 on the bodytransom 9 and made with flanges 10 at each side toprevent displacement of parts.

The body-transom 9 is provided with a contral depending circular tongue 11, mounted in a depressed pocket or guide 12 in trucktransom 1, and a' kingbolt 13 is passed through tongue 11 and bottom of pocket 12 and has a nutlt screwed thereon to limit the upward movement of the tongue and prevent its-escape from the guide or pocket, While the latter serves to prevent independent movement of the transom laterally 0r longitudinally, but will not interfere with slight pivotal or rolling motion of the body-transom or the truck in turning.

It-will be seen that with my improvements I dispense entirely with the truck-bolster and support the body-transom directly on springs through the medium of the side bearings, which latter permit slight rolling movement atvboth ends owing to their rounded ends being in engagement with the flat surface of the cap 6 and the bearings 8 of body-transom 9.

A great many slight changes and altera- 7,9 tions might be resorted to in the general form and arrangement of parts described without departing from my invention, and hence I do not wish to be limited to the precise construc tion set forth, but consider myself at liberty to make such slight changes and alterations as fairlyfall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a car-body and side truck-frames, of a bod y-transom depending from the car-body, a truck-transom connecting the side frames, springs within'the trucktransom and rocking bearing-pieces resting on said springs and engaging at their upper ends the under face of the body-transom.

2. The combination with a truck-transom, of springs therein, a car-body,a body-transom 0 depending from the car-body, rocking side bearing-pieces supported on the springs in the truck-transom, and having bearings at their upper ends against the under face of the body-transom, 5

3. The combination with a truck-transom, of springs carried thereby,caps on the springs, a body-transom pivotally connected at its center to the truck-transom and side bearingpieces having a rocking or rolling engage- 10o ment with the under face of the body-transom and resting upon the caps covering the springs, substantially as described.

4:. The combination with a. hollow trucktransom, of springs therein, a body-transom, and side bearing-pieces having a rolling or rocking engagement with the under face of the body-transom, and projecting into the truck-transom and supported on the springs.

5. The combination with a truck-transom having a central pocket or guide, of a bodytransom, a central depending tongue on the body-transom projecting into said pocket or guide, a king-bolt pivotally securing the tongue in the pocket, springs in the trucktransom near its ends, caps on the springs, and side bearings between the caps and bodytransom and rounded or curved at both ends, substantially as described.
